To all whom it may concern: from the line 3 3 of Fig. 1. Fig. 4- is a per Be it known that I, HENRY GEISENHONER, spective of one of the separators.

To this 5 5 and useful Improvements in Space-Blocks, are attached the separators C, each of which (Case No. 983,) of which the following is a consists of a strip of soft iron, such as is specification. shown in Fig. 4.

The parts are struction by which they may be readily made assembled by passing the loop C through one from magnetic material with considerable of the loops A'and the loop C through the saving in cost and the consequent advantage other one upon the opposite side of the strip 65 derived from the use of iron.
